Is there a way to have Calendar.app display its week numbers using the standard ISO 8061 week definition?
The standard says a week starts on Monday, and the first Thursday of the year defines the first week. So at the end of 2015, the standard week of 2015-12-28 to 2016-01-03 is
Week 53. In contrast, Calendar.app in Yosemite & Mountain Lion shows
- What definition of week is Apple using? Perhaps simply the First of January is always Week 1?
- Is there any way to change this default behavior to show standard weeks?
